His research interests are in the fields of global environmental change and extinction events, and his involvement in the deciphering of the events around the Cretaceous-Tertiary boundary event is documented by a series of publications (from 1997to 2019). He also explored the sedimentary documents of the PETM the Paleocene-Eocene boundary event (from 2000 to 2019). He is also involved in the study of oceanic anoxic event (from 2001 to 2018). His interests are in the use of geochemical and mineralogical proxies, such as stable carbon and oxygen isotopes, organic matter, clay minerals and recently also trace metal distributions as indicators of environmental and climatic change at the time of the extinction events. One of his main actual interest is the link between LIPS activity and mass extinction events, in particular during the KPg mass extinction. His team provided the most accurate dating of the Deccan activity and highlighted its crucial role in the KPg extinction. The use of mercury as a tracer of volcanic activity is also part his research. Acidification linked with these events is also one of his recent interest, more particularly for the KPg mass extinction.

He leads the sedimentaryorganic matter research group focusing primarily on the accumulation, distribution, and diagenesis of sedimentary organic matter in time and space and how they can be employed to characterize petroleum systems through the interpretation of depositional paleoenvironments, kerogen type, and organic thermal maturity. Dr. Zobaa’s research also includes the identification and delineation of key paleoclimatic and biostratigraphic events in the earth’s history that were responsible for the production and preservation of large organic matter quantities in some of the world’s hydrocarbon most producing sedimentary basins.Mohamed Zobaa utilizes palynology and palynofacies analyses as primary proxies in his research but engages other disciplines and integrates a variety of tools to support and corroborate his research findings. These include, for example, Rock-Eval Pyrolysis, XRD, XRF, Vitrinite Reflectance, Gas Chromatography–Mass Spectrometry (GC-MS), and Organic Petrology. Dr. Zobaa has about 18 years of research experience studying the stratigraphy, palynology, and sedimentary organic matter content of many of the most important hydrocarbon generating sedimentary provinces in the world (e.g., Deep-water Gulf of Mexico, the Permian Basin in Texas, the San Juan Basin in New Mexico, the Williston Basin in North Dakota, and the north Western Desert of Egypt). Additionally, his research results and methodologies have been published and documented in top-tier, prestigious and widely circulated professional journals both in the United States and internationally. Some of these include the Geological Society of America Bulletin, Geosphere, Sedimentary Geology, and Marine and Petroleum Geology.Dr Haytham El Atfy is associate professor at Mansoura University, Egypt, from which he has received a BSc in geology and an MSc in palynology. He has obtained his PhD in geosciences (palynology and organic geochemistry) from Goethe University, Frankfurt, Germany, in 2014.

His scientific contribution is resulted in a number of more than 30 articles that have been mostly published in international, peer-reviewed journals that have a good scientific reputation. In addition, he has also strong skills in laboratory work including, palynology, palynofacies analyses, thermal maturation index, spore-pollen coloration index (SCI) and organic petrography. He is also a Visiting Researcher at the Senckenberg Research Institute, Germany and UNIVATES, Brazil.Beyond his research interests, he is a trainer in academic skills, such as academic writing, writing for funding, proposal writing and quality assurance and accreditation since 2018.
